CHARLES WENDELKEN,

OF ROBSTOWN', TEXAS.

i CHECK-WRITER.

Be it known that I, CHARLES VENDELKEN, a citlzen of the United States, residing at Robstown, in the county of Nue'ces and State of Texas, have invented certain new and useful Improvements in Check-\Vnters; and

I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to typewriters, and more especially to machines of that kind as disclosed in my Patents Nos. 1,340,428 and 1,340,429 granted May 18, 1920.

It is the object of the invention to provide a novel and improved machine for typewriting bank checks, notes and the like, in a convenient and facile manner by the single movement of the sheet or blank through the machine, the machine having two sets of type and being operable whereby one set of type can be operated to print or impress the payees name as well as the amount in numerals, after which the other set of type can be operated for printing in words the amount, although the two sets of type can be of various characters for typewriting different lines on the sheet or blank during a single movement thereof through the machine.

As a more specific object, the invention aims toprovide such a machine embodying type cylinders mounted for sliding and rotary movements with key-operated means for shifting or sliding said cylinders to bring the selected characters to printing position and then rotating the cylinders to print the selected characters, with provision for shifting from one cylinder to the other so that they can be operated in succession to print the successive lines on the sheet or blank.

Another object is the provision of such a machine in which the turning movement of the type cylinders will automatically feed the sheet the required distance, according to the length of the character being printed, thereby moving the sheet step by step without special variable spacing means for this purpose, the cylinders being rotated the same amount for each operation, thereby Specification of Letters Patent. Patented June 28 1921 1920. Serial No. 395,708.

eliminating the necessity for such variable spacing sheet-feeding means and simplifymg the construction accordingly.

A. further object is the provision of novel means for rotating the type cylinders to do the printing or make the impressions and then return them to initial position, and a further object is to provide a safety device compelling the complete rotation of the type cylinders, in order to avoid a partial or incomplete rotation thereof should the keys not be depressed sufficiently and requiring the operator to depress the keys the required amount to assure of proper operation of the machine.

A still further object is the provision of novel key-operated means for shifting or slidmg the type cylinders the required amounts for printing the selected characters according to the keys that are depressed, and resulting in the type cylinders being shifted to proper position before said cylinders are rotated to make the impressions.

A further object is the provision of means for changing from one type cylinder to the other, whereby they can be shifted by the keys in succession, to use one cylinder for printing on one line of the sheet, and then to use the other cylinder for printing the next line.

A further object is the provision of novel means for shifting the type cylinders variable distances according to the keys depressed, before rotating said cylinders and for locking the rest of the type bars or levers against depression when one of them is depressed thereby avoiding confusion in the operation of the machine by the simultaneous depression of two or more keys, or the depression of one key while another one is depressed.

Vith the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts hereinafter described and claimed, it being understood that changes can bemade within the scope of What is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a plan view of the machine,

Fig. 11 is a sectional detail taken on the line 11-11 of Fig. 10.

Fig. 12 is a perspective view of one of the type cylinders, a portion thereof being broken away.

A suitable casing or frame 15 is provided. and a bank of character keys 16. and also a shift key 17 for changing or shifting from one set of type to the other. The top of the casing 15 has parallel longitudinal typecylinder housings 18, which are convexed transversely, and said top of the casing has a transverse table 19 extending underneath the housings 18. said housings having lower slots or openings 20 at the opposite sides above said table for the passage of the check or other sheet 29 through or under said housings on the table for the successive printing operations. The sheet moves from the right to the left, and the table 19 is provided at the right hand end with an adjustable sheet guide 21 to start the sheet through the machine in the proper position for printmg.

The printing is done or the 1IIII'HCSSiODS made by means of a pair of parallel longitudinal type cylinders 22 and 23 located within the housings 18 above the table 1.). and mounted for longitudinal sliding or shifting movement on parallel longitudinal shafts 2 1 mounted for rotation within the casing. Said cylinders are feathered or splined on the shafts to rotate therewith. The right hand cylinder 22 contains the let ters of the alphabet, digits and other charactors, in the embodiment of the machine as shown, for printing the payecs name and amount of the check or note in numerals on the payees line 30 of the sheet 29, while the type cylinder 23 at the left contains word type and other characters for printing out the amount in words with appropriate designations and characters. The type 25 of the cylinders are raised from the peripheral surface thereof and are adapted to make the impressions on the sheet 29 at the point where it passes over the platens. As shown, roller platens 26 are employed, the same being carried for rotation by the table 19 under the shafts 2% of the type cylinders at the points where the impressions are to be made, the roller platen 26 of the type cylinder 22 being located on the payees line 30 of the sheet 29 which moves on the table 19, while the roller plate-n 26 of the type cylinder 23 is located at an offset longitudinal position on the amount line 31 of the check or sheet 2!). Thus. when the type cylinders are shifted, the characters which pass over the platens 26 during the rotation of the cylinders. are the ones which print on the sheet 25), and the type can be such as used in check writers or protectors which perforate or shred the characters in the sheet or blank. to prevent alterations. The type characters are raised from the peripheral surfaces of the cylinders. so that when said type. contact with the sheet over the platens 26. the sheet will be advanced an amount equal to the peripheral length of the type. thereby automatically advancing the sheet according to the characters printed. and the rotation of the type cylinders thus provide both the impressions and the required variable spacing of the sheet as the type cylinders are rotated. lnking rollers 27, or the like. are carried by the housings 18 near the roller platens 26, whereby to ink the type which are. moved over said platens to make the impressions, and the housings 18 have openings or windows 28 exposing indices 28 on the cylinders 22 and 23. These indices are arranged in longitudinal series on the upper surfaces of the cylinders, and are arranged according to the type, whereby when said cylinders are shifted. the operator is advised of the character to be printed by the exposure of the corresponding index through the opening or window 28. In this way. the operator is advised, before the printing is done. which character will be printed. inasmuch the indices on the type cylinders are exposed through the openings or windows 28 when said cylinders are shifted to printing position, thereby avoiding mistakes.

The type cylinders are shifted directly by means of levers 32 within the frame at the rear end thereof connected by links 33 and swivel joints 34: with the rear ends of the type cylinders, and springs 35 connected to the levers 82 return the type cylinder to normal forward position.

The rearward movement of the levers 32 will shift the type cylinders to printing position, and the various characters are printed according to the positions that the cylinders are moved, to bring the respective characters over the roller platens 26.

The type cylinders are rotated directly from bevel pinions 36 and 37 secured on the shafts 24 and meshing with the respective bevel gear wheels 38 and 39 rotatable on a transverse shaft 40 mounted rigidly in the casing. The gear wheels 39 are of larger diameter than the gear wheels 38, whereby the same angular movement of the gear wheels will rotate the type cylinders a greater amount than when rotated by the gear wheels 38 as will hereinafter more fully appear.

The key bars or levers 41, one for each key 16, are fulcrumed on the shaft 40, and a rocking frame 42 underneath said key bars is similarly fulcrumed on said shaft, and said key bars and frame are yieldingly raised by means of springs 43, the upward movement of said bars and frame being limited by suitable stops 44. The depression and return movement of the rocking frame 42 turns the gear wheels 38 and 39 for rotating the type cylinders, and ratchet devices or connections between said frame 42 and gear wheels are used. Thus, reversed ratchet wheels 46 and 47 are secured to the respective gear wheels 38 and 39, and the frame 42 carries reversed pawls or dogs 48 and 49 engageable with the respective ratchet wheels 46 and 47. Therefore, the depression of the frame 42 will cause the pawls 48 to turn the ratchet wheels 46 and gear wheels 38 whereby said gear wheels 38 in meshing with the pinions 36 will turn the type cylinders through an angle of say about ninety degrees. Then, during the upward movement of the frame 42, the pawls 49 in engaging the ratchet wheels 47 will rotate the gear wheels 39, thereby rotating the pinions 37 and type cylinders to complete the rotation thereof. The gear wheels 38 and 39 mesh with the respective pinions 36 and 37 on the opposite sides, whereby the rotation of the gear wheels 38 and 39 in opposite directions will rotate the type cylinders in the same direction, and the gear wheels 39 being of larger diameter than the gear wheels 38, will rotate the type cylinders through a larger angle than when rotated by the gear wheels 38. Thus, gear wheels 38 advance the type cylinders through an angle sufficient to do the printing of the longest character or word, and this movement of the type cylinders is always the same for every character, inasmuch as the sheet is only fed or advanced a distance equal to the length of the character being printed. Then, w n the frame 42 retu ns r ra ses,

the rotation of the gear wheels 38 will rotate the type cylinders in the same direction to complete one revolution thereof, and return the type cylinders to initial position for the next printing operation.

The rocking or depressible frame 42 has a transverse series of screws 45 by means of which the frame is depressed by the key bars 41, as will hereinafter more fully appear.

A safety device is used, which requires the complete oscillation of the frame 42, in order for the machine to operate, thereby avoiding the incomplete or partial rotation of the type cylinders, which, if it occurred, impair the operation. This device includes a pair of reverse ratchet wheels 50 and 51 secured on the shaft 40, which is non-rotatable, and a pair of stop pins 52 are carried by said ratchet wheels. A rocker 53 is carried by the frame 42 and has the reversed oppositely-extending dogs 54 and 55 alternately engageable with the respective ratchet wheels 50 and 51, as seen in Figs. 7 and 8. The rocker 53 also has an arm 56 projecting between the stop pins 52, whereby the oscillation of the frame 42 will bring the arm 56 into contact with the pins 52 alternately, to oscillate the rocker 53. Said rocker also has another arm 57 connected by a contractile spring 58 with a finger 59 secured to the shaft 40, and said arm 57 is so arranged that when the rocker 53 oscillates, the spring 58 moves past the axis of said rocker, or dead center, whereby to cause said rocker to snap to either position when moved past intermediate position, and to retain the rocker in either position. Thus, when the frame 42 is depressed. with the rocker 53 in the position shown in Fig. 7, the dog 54 drags on the ratchet wheel 50, thereby preventing the frame 42 from rising until the dog 54 is released. When the frame 42 is completely depressed, the arm 56 contacts with the forward pin 52, thereby stopping the movement of the arm, and the movement of the rocker 53 with the frame 42 will cause the rocker to swing on its axis, past intermediate position, whereby the spring 58 comes into play for disengaging the dog 54 from the ratchet wheel 50, and engaging the dog 55 with the ratchet wheel. 51. Coir sequently, when the frame 42 has been completely depressed, the dog 54 is released, thereby enabling the frame to-rise, and the dog 55 in dragging over the teeth of the ratchet wheel 51, will prevent the frame being depressed until the dog 55 is released. hen the frame 54 is completely raised, the arm 56 in contacting with the rear pin 52, as seen in Fig. 8, will cause the rocker 53 to swing on its axis as the frame completes its upward movement, thereby swinging the dog 55 away from the ratchet wheel 51 and swinging the dog 54 toward the ratchet wheel 50, the spring 58 causing the rocker to return to the position, as shown in Fig. 7. This device therefore locks the frame 412 against incomplete movement in either direction by requiring the full stroke or movement of such frame downward and upward, in order that the type cylinders will be given the full rotary motion. This double ratchet device thus alternates or reverses to prevent the reverse movement of the frame 12 when swung in either direction, but enabling said frame to reverse when it has made a full movement in either direction, thereby reversing the ratchet device. This affords a safety feature, in that the frame 12 will be locked if not given a full movement, thereby assuring of the proper operation of the machine, and requiring the com plete depression of the keys 16.

The type cylinders 22 and 28 are shifted by means of a pair of U-shaped levers 60 and 61, respectively, having their lower portions connected by the respective links 62 and 63 with the levers 32, and the terminals of said levers 60 and 61 are mounted for oscillation on a transverse nonrotatable shaft 64 mounted within the casing forwardly of the shaft 10. The levers 60 and 61are disposed side by side in front of the respective type cylinders, and the key bars 41 and frame 42 extend through said levers 60 and 61 under the shaft 64:. Forwardly projecting arms 65 are mounted for oscillatory movement on the shaft 641 near the opposite ends thereof, and a transverse rod 66 has its terminals secured to the forward ends of said arms, thereby formin an oscillatory yoke mounted on the shaft 6 1, which is operated by the key bars for oscillating either of the levers 60 and 61 to shift the corresponding type cylinder. Means is provided for alternately connecting the levers 60 and 61 with the arms 65, and for this purpose the arms 65 have the segments of ratchet teeth 67, and pawls 68 and 69 are carried by the opposite terminals of the levers 60 and 61 to drop into engagement with the ratchet teeth 67, whereby the downward movement of the arms 65 will, through the medium of the pawl 68 or 69, swing the corresponding lever 60 or 61 rearwardly. The pawls or dogs 68 and 69 are alternately engaged with the ratchet teeth 67, and are provided with the respective lugs 7 O and 71, and bell crank levers 72 and 7 3 are mounted for oscillation on the shaft 6 1 and have fingers 7 5 to contact with the lugs and 71, whereby to raise the pawls or dogs 68 and 69. The lever 73 is connected by a link 76 with the shift bar or lever 77 having the shift key 17, and secured to a transverse rock shaft 78. An arm 80' secured to said rock shaft is connected by a link 79 with the lever 72, and the arrangement is such, that when the shift bar or lever 77 is raised, the lever 73 is swung away from the lug 71,

thereby releasing the dog 69 so that it drops into engagement with the respective teeth 67 thereby connecting the lever 61 with the arms 65 and rod 66, the lever 72 being swung so that it contacts with the lug 70 and raises the dog 68 so that the lever 60 is disconnected from the arms 65 to remain idle. By depressing the bar or lever 77, the lever 73 is swung so that its finger contacts with the lug 71, and raises the dog 69, thereby releasing the lever 61 so that it will remain idle, and the lever 72 is swung away from the lug 70, thereby releasing the dog 68 so that it can drop into engagement with the corresponding teeth 67, thereby connecting the lever 60 with the arms 65. Thus, by raising or lowering the key 17, the levers 60 and 61 can be selectively or alternately connected to the actuating arms to shift either type cylinder according to the will of the operator. cured to the rock shaft 78 has a spring 82 connected to it, for normally raising the bar or lever 7 7 and the ley er or bar 77 when depressed can be engaged under a catch 83. Thus, the spring 82 holds the shift mechanism or device in one position, while the catch 83 will hold it in the other position.

In order that the depression of the various key bars or levers 41 will depress the rod 66 and arms 65 variable distances, according to the characters printed, whereby to shift the type cylinders to the proper longitudinal positions, tripping members 84 are individually pivoted, as at 85, to the key bars 11 and eXtend upwardly therefrom, being provided with the abutments 86 to swing rearwardly against the rod 66, and said abutments have hooks 87 extending rearwardly and overhanging said rod to hook over or engage same. The members 84 have shoulders 88 below the abutments 86, and said members also have arms 89 below the key bars 41, with expansion springs 90 between said arms and key bars,

which normally swing the members 84: to bring the abutments 86 against the rod 66. The arms 89 contact with the screws 45 when the leey bars are depressed, which serves a double purpose. First, when a key bar is depressed, as seen in Fig. 3, the arm 89 of the corresponding member 84.- will contact with the corresponding screw 4155, thereby stopping the movement of the arm 89, and causing said member 84 to swing forwardly to remove the hook 87 from over the rod 66, as seen in said Fig. 3. Thus, when a key bar is depressed, the hook 87 will pull the rod 66 downwardly with the member 84 of said key bar, thereby swinging the arms 65 downwardly, until the member 84 is released from the rod 66 by the contact of the arm 89 with the corresponding screw 15. Then, the continued downward movement of the key bar will depress the frame 42 by An arm 81 se-' the contact of the arm 89 on the corresponding screw 45. The screws are adjusted according to the arrangement of. the char acters on the type cylinders, whereby the members, 84 are disengaged from the rod 66 at different points of the downward movement of the key bars, whereby the type cylinders are shifted rearwardly accordingly. In other words, the arrangement is such that when a key bar is depressed, the member 84 thereof will pull the arms 65 downwardly and swing either the lever 60 or 61 rearwardly sufliciently to shift the type cylinder to position with the selected character in position for printing, at which time the arm 89 of the member 84 in contacting with the properly adjusted screw 45, will cause said member to swing to disengage the hook 87 thereof from the rod 66, thereby stoppingthe downward movement of the arms 65. Then, the movement of the members 84 with respect to the key bars being limited, the further downward movement of the key bar which is depressed will depress the frame 42, for rotating the type cylinder. It is evident, therefore, that by the adjustment of the screws 45, the shifting of the type cylinders is regulated.

A second safety device is employed, for preventing the conflicting operation of the machine by the depression of a second key when one key has been depressed, and also for the purpose of retaining the corresponding cylinder in its proper shifted position for printing until the depressed key is returned. This safety device comprises a transverse rod 91 parallel with and adjacent to the rod 66, and provided at its terminals with arms 92 pivoted to the arms 65, and connected by links 93 with dogs 94 also pivoted to the arm 65 and having the toothed portions 95 to engage the toothed segments 96 of disks 97 secured on the shaft 64. Springs 98 are connected to the dogs 94 and exert to move a tension to move said dogs into engagement with the toothed segments 96. In normal position, with the arms 65 raised and the rod 66 contacting with the hooks 87, as seen in Fig. 4, the rod 91 bears against the abutments 86 immediately above the shoulders 88, thereby retaining the dogs 94 in released position out of engagement with the segments 96. hen one key bar is depressed, so that the corresponding hook 87 pulls the rod 66 downwardly, the rod 91 can immediately swing under the shoulders 88 of the other members 84 when the depressed member 84 is swung forwardly by the contact of its arm 89 with the corresponding screw 45, as seen in Fig. 3. The rod or retarder 91 in passing under the shoulders 88 of the tripping members 84, will resist or impede the depression of the second key while another key is depressed. Furthermore, the rod 91 in contacting up wardly against the shoulders 88, will prevent the spring 35 from returning the type cylinder and arms 65, inasmuch as the arms 65 are locked by the dogs 94 and the tension of the springs 98 offers sufficient resistance to overcome the tension of the spring 85 of either type cylinder with the parts in locked position, as seen in Fig. 3. However, when the depressed key bar is raised by its spring 43, the member 84 is swung rearwardly by its spring 90, and the abutment 86 in swinging rearwardly against the rod 91, will swing said rod rearwa'irdly, thereby, assisted by the tension of the spring 35, swinging the arms 92 rearwardly and moving the dogs 94 to releasing position, thus enabling the parts to return to normal position, the rod 91 passing upwardly with the abutments 86. It will be noted that when the tripping member 84 of any one of the key bars is de pressed. to release the rod 91 for movement under the shoulders 88 of the remaining members 84, the movement of the dogs 94 into engagement with the non-rotatable segments 96 will positively lock the arms 65 against movement, thereby preventing the shifting of the type cylinder either way until the arms 65 are unlocked or released.

The operation of the machine is as follows: The check or sheet 29 is placed on the table 19 at the right hand end against the guide 21 and is slid under the type cylinder 22, to the proper starting position. The machine is then operated similar to a typewriter for typewriting the payees name and the amount of the check in numerals on the payees line 30. Thus, to operate the right hand type cylinder 22, the shift key 17 is depressed and the lever 77 held depressed by the catch 83, thereby pulling the links 7 6 and 79 downwardly, and swinging the levers 72 and 73, to release the dog 68 so that it engages the respective teeth 67, while the dog 69 is raised. -This will connect the right hand lever 60 with the arms 65. lVhen the first key is depressed, it will depress the corresponding tripping member 84, so that the hook 87 thereof depresses the rod 66 and arms 65, thereby swinging the lever 60 rearwardly, to shift the type cylinder 22. lVhen the type cylinder is: shifted to bring the proper character to printing position above the corresponding roller platen 26 over which the sheet 29 rests, the depressed member 84 is swung rearwardly to releasing posit-ion by the contact of its arm 89 with the corresponding screw 45, thereby stopping the type cylinder at the proper longitudinal position, and the depression of the arms 65 will have moved the rod 91 to a position, so that when the depressed member 84 swings forwardly, the rod 91 will follow it and move under the shoulders 88 of the remaining members 84. This releases the dogs 94 so that the toothed portions thereof engage the segments 96, as seen in Fig. 3, thereby locking the arms (35 and type cylinder to the stationary shaft (34, and, furthermore, resisting or impeding the impression. of another key until the de pressed key is returned to normal position. In this way, the type cylinder is shifted longitudinally to the proper position by the first part of the depression of the key 16, and when the arm 89 of the corresponding members 84 contacts with the respective screw 45, the remaining movement of the key 16 will depress the frame 42, so that the pawls 48 in engaging the ratchet wheels 46 will rotate the gear wheels 38. The type cylinders are therefore rotated through an arc to do the printing, it being noted that one of the type cylinders remains in forward position so that the rotation thereof will not cause an impression on the sheet, thus eliminating the requirement for a selective connection with the type cylinders for rotating them, inasmuch as both of them can retate simultaneously, whereas only one type cylinder is shifted to printing position. Thus, the type cylinder which is shifted to printing position. is rotated through an are so that the corresponding character in passing the inking roller 27 is supplied with ink, and then contacts with the sheet over the corresponding roller platen 26. thereby making the impression and, at the same time, advancing the sheet a distance equal to the peripheral length of the character on the type cylinder, ready for the next character or impression. It will also be noted that when the type cylinder is shifted by the first depression of a key, the character to be printed is indicated through the corresponding opening or window 28, so that the operator can observe the indices to avoid mistakes. Then, when the key is released, the frame .42 in being raised by the spring 43 thereof will result in the pawls 49 turning the ratchet wheels 4;? and gear wheels 39 to complete the rotation of the type cylinders and restore them to normal angular position ready for the next operation, and the type bar 41. being raised, will enable the shifted type cylinder to return to forward position under the influence of the corresponding spring 35. Furthermore, the depressed member 8-f will swing rearwardly under the influence of its spring 90, when the arm 89 is removed from the corresponding screw 45, to swing the rod 91 and arms 92 rearwardly, thereby releasing the dogs 94, so that the arms 65 can swing upwardly under the influence of the spring 35 in returning the type cylinder and corresponding parts to initial position. The rod 91 is thus pushed rearwardly so as to move upwardly against the abutments 86, ready for the next operation. This operation is repeated until the name or other data has been typewritten on the line 30 of the sheet, and the sheet, during the first printing opera tion is advanced so that it passes under the second type cylinder 23, ready for the second printing operation on the line 31 of the sheet. The operator then releases the lever 77 from the catch 83. so that the spring 82 will raise the shiftlever 77, thereby disengaging the dog 68 from the arms 65, and releasing the dog 69 so that it engages the corresponding teeth 67, thereby disconnecting the lever (it) from the arms (35 and now connecting the lever 61 of the type cylinder 23 with said arms (35. Now, when the keys are depressed, the type cylinder 23 will be shifted to printing position instead of the type cylinder 22, and the second printing operation. is carried out substantially the same as the first one, excepting that the printing is done or the impressions made on the sheet on the second line 31 instead of the first line 30. The first type cylinder is preferably for printing the name of the payee or the like, and the amount of the check in numerals. while the second type cylinder is for printing the amount in letters, or the like, although the machine can be used for other suitable purposes, whereby printing can be done on more than one line of the sheet during a single movement thereof through the machine or in one direction. \Vhen the second line has been typewritten. the check is withdrawn from the left hand end of the table 19.

The double dog rocker 53, as hereinbefore described, requires the full oscillation of the frame 42 for the machine to operate, therefore assuring of the full rotation of the type cylinders during the movement of each key. Due to the fact that the rotation of the type cylinders automatically advances the sheet a distance to the peripheral lengths of the characters being printed. no variable spacing sheet-feeding means is required. thereby simplifying the operation, and it will be noted that as the sheet is advanced by the first type cylinder, itis moved to position for the impressions and advancing movement of the second type cylinder, each type cylinder printing on a separate line.

Having thus described the invention. what is claimed as new is 2- l. A typewriting machine comprising a pair of rotatable and shiftable type cylinders, arranged for the successive passage of a sheet past them, and having peripheral type for making impressions on the sheet and advancing the sheet. and means for shifting said cylinders to printing position for different characters and for rotating said cylinders.
